President Bush arrives in Uganda Friday on the fourth stop of his five-nation tour of Africa. The president will focus on efforts to fight AIDS.

The president's trip to Uganda is meant to highlight his five-year, $15 billion program to fight the spread of AIDS in Africa and the Caribbean.

After meeting with Ugandan President Yoweri Museveni, Mr. Bush will tour Africa's largest indigenous AIDS service organization in the town of Entebbe where counselors provide basic medical services to more than 30,000 patients a year across Uganda.

The organization also supports some 200,000 orphaned and vulnerable children with assistance from the U.S. Agency for International Development and the Centers for Disease Control and Prevention.

The president's AIDS program, which has not yet been fully funded by Congress, is based in part on Uganda's success in reducing the spread of the disease by focusing on what the president calls ABC, abstinence, being faithful and contraception.

Mr. Bush will then leave for Nigeria where he will spend the night before talks Saturday with President Olusegun Obasanjo that are expected to focus on U.S. support for a West African peacekeeping force being sent to Liberia.
